MACHINE FOR FILING CARRIAGE-TOP IRONS.

SPECIFICATION forming part of Letters Fatent No. 373,203, dated November 15, 1887 Application filed January 12,1886. Serial No. 188,357. (No model.)

To all whom, it may concern.-

Be it known that I, FRANK. SOHREIDT, of Mansfield, county of Richland, and State of Ohio, have invented a new and useful Im- 5 provement in Machines and Files for Filing Carriage-Top Irons, .of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, making part of this specification. v

My invention relates to the construction of i the machine, the arrangement of parts thereof,

and to the construction of the files employed.

in said machine for filing thejoints oi knuckles of carriage-top and other irons, as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure l is a perspective view of a machine embracing my improvements; Fig. 2, a front elevation of the file carriage and holder; Fig. 3, a plan view of the carriage for supporting and moving the iron to be operated upon; Fig. 4, an end elevation, and Fig. a front elevation, of said carriage and its support; Fig, 6, an end elevation looking at the opposite end to that shown in Fig. 4., with some of the parts removed; Fig. 7, a side elevation of the gripping-bar and its actuating camlever detached, and Fig. 7 a perspective view of the eocen tric for adjusting the gripping bar or lever; 0 Fig. 8, a side elevation of the means employed for adjusting the gage for setting the irons to be operated upon in proper relation to the carriagefor supporting said irons and moving them up to the action of the file. Fig. 9 is a perspective view of one end of a file employed, and Fig. 10 a similar view of another file of slightly different construction. Fig. 11 is a perspective view of the blank after it has been acted upon by the file.

A indicates a stout post forming a suitable support for the frame or heavy frame-bracket B, in .which the operative parts of my improved filing-machine are mounted, a second short post or posts, A, being, by preference, also employed to support and steady the outer edge of the table 0, on which the movable carriages rest and move for holding and moving'the work up to the files.

At a suitable height above the table 0' th frame plate or bracket B has a stout horizontal arm, B, terminating at its outer end in a vertical cross-head, B, which projects above and below the arm B, and may, if desired, connect at its lower end with a second horizontal arm located underneath and forming an additional support for the table 0. The

frame plate and arm or arms B have suitable In the upper ends of the frame-plate B and I V cross-head B, which project above the arm B in suitable bearings, is mounted a shaft, E, having a driving band-pulley, E, secured to it, and an idle-pulley, E mounted loosely upon it for throwing the shaft into or out of 7 action, a band, E serving to connect the shaft with any suitable motor. The end of the shaft, projecting beyond the bearing for the shaft in the arm or cross-head B, has a crank-wheel,

F, secured to it, provided with a crank wrist or pin from which a pitman, F, extends to and has its lower end connected with a pin on the carriage D, for imparting a reciprocating movement thereto. The carriage D is provided at top and bottom on its forward or outer face, and also upon its sides, if desired, with flanged socket-pieces a or, either formed on or secured to the sliding block or carriage D, and

in the sockets of which are secured file-holder bits b I), made adjustable in said sockets by means of adjusting screws 0 0', operating through the flanges a of the socket-pieces upon the ends of the bits b and b, and held at the desired adjustment by clamping bolts or screws 0 c,passing through slots in the bit-shanks and 5 into or through the holder D. The bits b b are beveled from opposite sides on their inner' adjacent ends into V shape to fit correspond ing sockets or grooves in the ends'of the files G, which are secured to the carriage by means rco thereof, with their concave sides facing outward from the side or face of the carriage to which they are attached, as shown. The files employed are of different constructions, according to the work required of them, that shown in Fig. 9 being the first used upon the knuckle in which the joint is to be formed after the first operation of upsetting the metal to form said knuckle. This requires the file or rasping surface only in the longitudinal groove or concavity g in its face, as shown, while in the construction shown in Fig. 10 the concave groove g has a file-surface, as have also the plane projections g at the sides of said groove, and the rabbeted edges or sides of the file, as shown at g and 9 for adapting the file to operate in the angles and upon the shoulders and sides of the knuckle or other protuberanee formed on the carriage-irons. The file carriage and holder D is shown adapted to receive a number of files, two in front and one at each side, but only one complete earriage for the irons to be operated upon isshown in Fig. 1, and that arranged at one side and shown enlarged and in detail in Figs. 3 to S, inclusive.

H represents a base-plate provided on its lower face with a longitudinal rib, H, of dovetail or other suitable form, adapting it to slide and be retained in a groove of corresponding form in the face of the table G, or in a fixed base-plate thereon, for giving it the longitudinal adjustment required to bring its inner end into the desired relation to the file. The inner end of this slide H has a boss or ear, h, formed on it near the center of its width, projecting in semi-cylindrical form and perforated vertically to receive a pin, h, through a second plate, I, resting on plate H, and provided with a similar boss, permitting the pivoted pin h to project one-half its diameter (more or less) beyond the ends of plates H and I. The upper face of the pivoted plate I has a longitudinal groove formed in it of dovetail or T shape, (inverted,) adapted to receive a tongue or rib, J, of corresponding shape, formed on the lower face of a plate, J, resting and adapted to slide longitudinally on the plate I. The upper face of plate or slide J is shown made angular in form, being for about half its width horizontal at j, and the other half, j, rising toward the opposite side in an inclined plane, as shown in Fig. 4. The adjacent faces of the plates I and J have a cylindrical socket formed in them at i, to receive a spiral spring, 1'', which abuts at one end against a shoulder in the plate I, and at its other against a pendent lip or flange, j formed on or secured to the forward or outer end of the slide J, the tension of the spring being exerted to force the slide outward, as shown in Fig. 5. The horizontal portion j of the plate J has a slotted or grooved bar, K, formed upon or secured to it, the inner edge of which forms a fixed vertical ledge or shoulder, 70, against which to clamp the irons to be operated upon, as will be explained.

The slot or groove extends longitudinally in or through the bar K, and has an adjustable gage-rod, L. located in it, held therein by a cap-plate, K, secured to the bar K by screws or other suitable fastening, and partly broken away in Fig. 3 to show the parts underneath. One end of this gage-rod L extends beyond the plate J at the inner end of the latter, and is bent into hook form at L, the end of the hook, when the gage is adjusted for the purpose, overhanging the clamping edge or shoulder k, and forming a stop against which the shoulder ofthe iron to be operated upon is thrust by the attendant for giving the iron the proper position on the slide J.

The opposite end of the bar L has one end of a short transverse lever, Z, pivoted to it, said lever extending out through a slot between the cap-plate and the outer rib or wall of the slot in which the gage-rod rests, and pivoted in said rib nearthe center of its length, as shown. The end of rod L, pivoted to lever Z, abuts against a disk, m, on the end of a yielding rod, m, sliding in a perforated sleeve or ear, forming an end wall to the slot or groove in the bar K. (See detail view, Fig. 8.) The rod m extends only partly through the sleeve k, and its projecting portion is surrounded by a spring, m, extending between the end of the sleeve It and the disk m on the end of the rod m, and serving to hold the rod thrust out, with the disk resting against the end of the rod L. The outer end of the perforation in the sleeve is is threaded to receive a screw, m provided on its outer end with a milled head or disk, m, for adjusting it, and with a jam-nut, m which, by being screwed up against the outer end of the sleeve 70, after the screw has been properly adjusted, prevents accidental movement or displacement of the latter. The rod or pin m, in setting the iron to be operated upon in the slide or holder J, is thrust inward against the end of the screw m and the adjustment of the latter serves to determine the position of the hook or gage L for setting the iron. The left-hand side of the slide J (to the operator facing its outer end) has a toothed rack, j, formed upon or secured to it, with which a toothed segment, 12, pivoted in a lug or ear, 1 on the plate I engages, said segment being provided with a handlever, n, for actuating it, and through it and the rack n imparting an endwise movement to the slide J. The segment n is provided on its upper face with an eccentrically-arranged pin, a with which the lever Z comes in contact as the slide J approaches the end of its outward movement, and the action of the latter, as the lever n is vibrated, causes the end of the gage-rod L to force the pin m inward until it is stopped by the screw on. The back of the gage-rod L near its hook end is provided with an inclined or cam-faced projection, Z, which, as the rod L is thrust inward for foreing the pin m against the screw on by the vibration of the lever n, as described, rides up on a cam-faced end of a small upright, 1, se-

operated upon, indicated in dotted lines inv said-figure. The iron is then clamped in position by means which will be described,whenthe attendant releases lever n, and the spring in forces the pin m and the gage-rod Loutward, the cam projection Z on the latter passes off the upright or spur Z and a spring, 1*, se-,

cured to inner side of the gage-rod L and bearing against the inner wall'of the slot or groove in which said rod rests, crowds its hook-gage back and away from the end of the iron to be operated upon, leaving the latter uncovered and free to be acted' upon by the file when its carriage or slide is moved into position for that purpose, as will be explained.

Upon the inclined face of the slide or carriage J is a clamping-lever, P, pivoted at or near the center of its length to said face by means of an adjustable eccentric sleeve or collar, 10, and a screw, 19 by loosening which i and adjusting or partially rotating the collar 10, by means of a milled flange or disk, 10, on its end, the lever P may be adjusted, as desired. The inner end of this lever has an angular jaw, P, formed upon it, having an angular socket in its lower edge adjacent to the ledge or rib is, for adapt-ing it to grasp and. firmly hold the iron to be operated upon against said ledge.

A spring, q, secured to the back of lever P, with its free outer end resting and pressing again'st'a pin, q, near the upper edge of the inclined iacej, serves, when its tension is not overcome, to force the clamp end P of lever P away from the opposing ledge k, for releasing and permitting the removal or introduction of an iron. The outer end of the lever P is bifurcated, forming ears at 10 between which is pivoted a cam or eccentric segment, Q, havinga lever,Q, formed upon it, by means of which it is vibrated, said lever having upon its end a ball or weight, Q, which, when the lever is vibrated downward for causing the jaw P to grasp the iron, serves to hold the lever until it is again vibrated in the reverse direction by hand for releasing the iron. The cam Q rests against and rides upon a boss or projection,J on the slide, J, for actuating the gripping-lever P. e

To the side or edge of the pivoted plate I, opposite the rack j a latch, r, is pivoted at its inner end, its outer freeend being beveled on its upper face at r, said bevel terminating in a square shoulder at r", adapted to engage a spur or pin, 8, on the corresponding edge of slide J when the latter is forced inward to until the operation of filing the iron is completed,when the attendant presses upon a handle, W, on the latch r, releasing the latter and permitting the slide to be retracted or moved outward by the spring 11 above referred to.

The iron to be operated upon is clamped between the ledge 7c and the jaw P, (indicated in Fig. 3,.) and is then thrust outward until the knuckle on its end. rests directly over on the head h of the pin h, through which the plate I is pivoted to the adjustable baseplate H and centered axially on but projecting beyond said head in such manner that by vibrating the plate I and the slide or carriage J on said pivot the entire rounded portion ofthe knuckle will be presented to and acted upon by the concave portion of the file, and where the file shown in Fig: 10 is used the shoulder and angle at the junction of said rounded end with the shank or body of the iron can also be sub jected to the action of the other portions of the file in a manner that will be readily under stood. 1

A washer, h of the required thickness is interposed between the pivotal car 13 and the head h of pin h for raising the head to the proper heightto properly support the knuckle or end of the iron resting thereon. The plate H has a laterally-projecting curved arm, H secu red to it, which serves to uphold the plate I when it is moved or vibrated laterally. The outer end of this arm rests on the table 0, and has a longitudinal slot formedin it at w,through which it may be adjustably secured to the table for steadying it and permitting its adjustment with the plate H, and the latter is held to the table 0 or baseplate thereon by a set screw or other suitable device, permitting its longitudinal adjustment for bringing the pivot-pin h into the desired proximity to the vertical face of the file.

Having now described my invention, I claim as new 1.
